Specification of Letters Patent. I Patented July 13 1915,

Application filed February 7, 1914. Serial No. 817,131.

To all whom it may concern:

citizen of the United States, residing at Chicago, in the countyof Cook and State of Illinois, have invented a certain new and useful Improvement in Reproducing Devices for Phonographs, of which the following is a specification.

This invention relates to reproducing devices for phonographs and has for its object to provide a new and improved device of this description.

There are two general types of disk phonograph records. In one of these general types of disk records, the needle of the re producer is moved laterally to vibrate the diaphragm of the reproducer, While in the other general form, the needle is moved up 111 depth. Under these conditions, one type of record cannot be played upon the machineadapted for the other type.

One of the objects of my invention is to provide means by which both types of rec- 0rd can be played upon one machine.

Referring now to the drawings, wherein one form of my invention is illustrated; Figurel is a side view of a device embodying my invention used in connection with a reproducer for a record having a laterally varying groove. so as to permit said reproducer to be used on a record having a depth varying groove; Fig. 2 is a rear view of the frame or support, adapted to be removably attached to the body of the reproducer; Fig. 3 is an enlarged View of the lower end of the frame shown in Fig. 2,

on the type of record having a laterally varying groove, such as a Victor reproducer. This rcproducer ha the sound box with the-diaphragm a, movably mounted upon the clamping part.

type, the record is made by a groove varying.

the arm 3 of the machine in any desired manner. The needle 4 is connected at one end to the diaphragm and has the usual pi otal connection at 5' with the casing of the sound box. The point 6 of the needle is adapted to pass along the groove when a record with a laterally varying groove is used, thereby causing the diaphragm 2 to vibrate. When it is desired to use this reproducer with a record having a groove varying in depth, the attachment illustrated in Fig. l is fastened thereto. This attachment consists of a frame or support having a clamping part 7, which is preferably a spring part, the ends of which are separated and connectedby. the screw 8, which may be loosened or tightened to clamp or unclamp Connected with the clamping part is an arm 9, having a laterally projecting part, which is preferably right-angular in shape, having the two branches 10 and 11, see Figs. 2 110.5.

The parts 9, 10 and 11 form a frame or support for the moving parts of the device. Movably connected with this frame is a rocking piece 12. As herein shown, the rocking pieee12 is fastened to a spring piece 13, which in-turn'is fastened to the branch 10 of the supporting device. The spring piece 13 is cut away at 14, so as to form the comparatively narrow supporting end 15 for the piece, said supporting end having the metal cut away to form the groove 16 to make the spring piece more elastic. so that when pressure is applied to the end 15, the

- spring piece responds to said pressure and permits the rocking piece to be given the proper motion. Connected with the rocking piece 12 is a projection 18. which in the construction shown is the head of a screw. This projection is received into a hollow receiving piece 19, attached to the vibrating arm 20, carrying the groove engaging point 21. This projection 18 and the hollow receiving piece 19 form a rocking connection between the vibrating arm 20 and the piece 12. The vibrating arm 20 is movably connected to the branch 11 of the support, preferably by universal joint. As, herein shown the sound vibrating arm 20 is connected by pivot 22 to a bracket 23, which is movably connected with the branch 11 by the pin 24-. The pivot .32 permits vertical movement of the vibrating arm and the pin it permits lateral movement of the vibrating arm. A retaining spring 25v is connected-with the vibrating arm and the pin 24 to hold the arm in direct contact with the projection 18 at all times. This retaining spring holds the vibrating arm so that the projection 18 projects into the receiving part 19 when the device is not in use, thus keeping the parts in their proper relation. The point 6 of the needle 4: rests upon the rocking piece 12, said piece being preferably provided with a groove 26 for. receivingthe point of the needle.

a Asshown in Fig- 5, the needle 4 engages the rocking piece 12 at one side of its center and said rocking piece is connected at the other side of its center with the vibrating. arm 20. The groove engaging point 21' preferably consists of a diamond, garnet or other hard material and when made of a precious stone, the stone maybe set in any varied in many particulars and some of the parts omitted and others used with parts not herein shown,- without departing from the The groove engaging point 21 is moved up spirit of my invention.

The use and operation of my invention are as follows: When is desired to use a record having a grooje varying indepth, the clamping part 7 is clamped upon the sound box 1 and the point 6 of the needle" 4 placed in the groove 26 of the rocking piece 12. The groove engaging point 21 is then placed in the groove of the record and the machine started up in the usual manner.

and down as it moves along the groove in the record, thus causing the arm 20 to vibrate. The vibrations of this arm are conveyed to the r cking piece 12, so as to rock said piece, thereby movingthe needle 4 laterally so as to actuate the diaphragm 2 and cause a reproduction of the sound. It will be seen that in this construction the up and down movement of the engaging point is converted. into a lateral movement at the point of the needle 4, thereby permitting the reproducer adapted for the records with 1 laterally varying groovesto be used in connection with records having grooves varying in depth;

It will be seen that by the particular construction illustrated, the vibrating arm is free to move up and down and laterally and this 'movement is not interfered with by connection with the rocking piece, on ac count of the rocking connection therewith. I have found that by means of this device,

. L EE the records having grooves varying in depthmay be used with the reproducer of a phonograph adapted for records having laterally varying grooves and that the sounds are reproduced accurately and in all their details, without scratching or unusual noise and that in fact the result produced is greatly superior to the result produced when the reproducer is used'onthe recordwith the laterally varying grooves for which it is adapted.
